> The background operations thread in DocumentNodeStore blocks writes to ensure a correct sequence of revisions introduced by local and external commits. Within this synchronization block the thread also invalidates caches.  OAK-1156 introduced a selective cache invalidation logic, which only invalidates documents that changed, but also comes with additional cost because it will make calls to MongoDB.
